Abstract: ABSTRACT          Asymmetric Synthesis Of .alpha.-Substituted-.alpha.-cyanomethyl Alcohols The invention concerns a process for the pre-paration of an  .alpha. substituted- .alpha. -cyanomethyl alcohol enantiomer of formula I                                             I   wherein the group R1 is an alkenyl, alkynyl, aryl or heteroaryl group by reacting an aldehyde of formula II                                             II   with hydrogen cyanide in the presence of a cyclic dipeptide enantiomer at a temperature below ambient temperature.       The process enables the preparation of compounds of formula I in high yield and high enantiomeric excess. The enantiomers of formula I may be used as intermediates for the preparation of chiral pyrethroids and chiral arylethanolamines.       The invention also embraces cyclic dipeptide enantiomers, processes for the preparation of chiral pyrethroids and chiral arylethanolamines from  .alpha. -substituted- .alpha. -cyanomethyl alcohol enantiomers of formula I and chiral pyrethroids and chiral ethanol-amines and the chiral pyrethroids and chiral ethanol-amines prepared thereby.

Abstract: ABSTRACT      A microcomputer (104) having predetermined clock pulse frequency requirements receives pulses from a multiplying type frequency synthesizer (200) which utilizes a reference frequency less than the largest of the predetermined requirements.  The synthesizer (200) is responsive to program instructions to generate clock pulse frequencies sufficient to satisfy the requirement for immediate execution of programmed tasks.  As the execution requirements change, the synthesizer (200) responds to provide only the frequency required.  Thus, the power dissipated by the entire microcomputer system is minimized.

Abstract: Abstract of the Disclosure An integrated shredder/plow combination for reducing trash to facilitate its being mixed with the soil by the action of the trailing plow portion of the combination is disclosed.  The shredder portion includes a unique arched structure positioned above a housing enclosing the shredder's cutting blades which permits the plow's drag to be transmitted directly to the tractor hitch so as to bypass the shredder assembly.  The shredder assembly is thus not subjected to the large longitudinal forces associated with plowing operations as well as the high side loading encountered during turns and as a result of ground contour.  This prolongs shredder operating lifetime and increases its reliability.  By positioning the plow assembly immediately aft of the shredder mechanism, the cut-up vegetation, or trash, is more effectively turned under as it is in an agitated, suspended condition when it encounters the burying action of the trailing plow assemblies.  The shredder/plow combination includes tractor-operated hydraulic cylinders in combination with transport wheels to facilitate transport of the shredder/plow combination to and from the work area.  The shredder portion is driven by a power supply shaft prom the tractor via a gear box and includes drive belt tension adjustment means for selecting the rotational drive force applied to the shredder's rotor.          In addition, the shredder portion may be detached from the plow portion of the combination and easily installed between a tractor hitch and a conventional tool bar assembly.

Abstract: METER OVERDRIVE PROTECTION CIRCUIT           Abstract A meter overdrive protection circuit is provided using a variable duty cycle drive pulse.  Such meters usually comprise speedometers and tachometers used in highway vehicles such as trucks.  A programmable pulse generator is utilized to provide a series of pulses of a selected width depending on the truck model.  A sensor input corresponding to the rate of rotation of the drive shaft of the truck is used to trigger the pulse generator to produce each output pulse.  Such output pulses are supplied to a meter drive which, based on the time average value of the output pulses received, displays an output value related to the rate of rotation of the truck drive shaft.  Upon the triggering inputs exceeding a preselected frequency, a microcomputer will change the pulse generator operation to a fixed duty cycle operation whereupon the meter will be held to a full scale deflection.  When the triggering inputs decrease below the preselected frequency, the pulse generator will be returned to a triggering output mode.  Such meter drive circuit protects electromagnetic meter needle movement from damage due to full scale pinning against a mechanical stop.

Abstract: ABSTRACT             ADAPTIVE CONTROL TECHNIQUE FOR A DYNAMIC SYSTEM      A controller for a voice coil motor driven disk file actuator is described.  The device has an online adjustable gain characteristic for controlling movement of the actuator assembly and an estimator that estimates actuator velocity and bias. Forward gain is estimated from position and coil current measurements and compared with a nominal value to create an error signal used to adjust the controller and estimator gain characteristics.  The control technique allows changes in the open loop system without changing the closed loop performance.  By monitoring loop gain it is possible to alter compensator gains to maintain a constant closed loop performance.
